Students investigate what it means to be alive. Students sort items into three categories: living, nonliving, or once living. Yeast and cornmeal are similar looking powders and students will conduct an experiment to see if either powder is alive. A terrarium is used to demonstrate to students that living, nonliving, and once living materials all interact in an ecosystem.

In this activity about light and perception, learners create pictures in thin air. Using a simple set up of a slide projector, slide, moveable screen or poster board, and a "wand", learners investigate how we see projected images such as those from movies and television. Use this activity to help learners understand concepts associated with light and optics including persistence of vision, reflection, and map projection.

This class is a global survey of the great transformation in history known as the "Industrial Revolution." Topics include origins of mechanized production, the factory system, steam propulsion, electrification, mass communications, mass production and automation. Emphasis on the transfer of technology and its many adaptations around the world. Countries treated include Great Britain, France, Germany, the US, Sweden, Russia, Japan, China, and India. Includes brief reflection papers and a final paper.

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic potential energy are further clarified through charts showing kinetic, potential, and thermal energy for each spring. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments in which students learn through exploration. All of the sims are freely available from the PhET website for incorporation into classes.

Children will do an activity that fosters conversations around the cause and effect of push and pull activities.

Students will observe as the teacher performs a variety of chemical and/or physical reactions. The teacher will guide a discussion that reinforces the concepts that atoms and molecules are too small to see but that we know about them through their behavior.

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this clip, the Micronauts explore the vast populations of filter feeders in the open waters of ponds. While exploring, they must escape the powerful feeding currents of these filter feeders. During this adventure, they also explore the special adaptations of algae and water fleas. Part 1 of the Microscopic Monsters Series.

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this clip, the Micronauts explore the process of photosynthesis. They conduct experiments using paramecium by observing the green algae cells within its body. Through their experiments, they realize the in the presence of light, the green cells generate oxygen and food molecules. Part 2 of the Microscopic Monsters Series.

The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While making a Downloadable docsary, the Micronauts discover the life-rich weedy shallows of the pond. They encounter single celled and multi-celled organisms, and a story unfolds of the diverse ecology found within ponds. Part 3 of the Microscopic Monsters Series.

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters Series.
